Claim of US Patent No. 11,071,118


1. A terminal apparatus comprising a wireless circuitry and a radio resource control circuitry, the terminal apparatus communicating with a base station apparatus by carrier aggregation using a plurality of cells including at least a first cell and a second cell, each of the plurality of cells having a different frequency, whereinthe wireless circuitry is configured to and/or programmed to:
receive, from the base station apparatus, a measurement configuration, wherein
the measurement configuration includes measurement objects and reporting configurations,
one of the measurement objects and one of the reporting configurations are linked by a measurement identity,
each of the measurement objects indicates a measurement frequency, and
one or more of the reporting configurations each include a criterion related to event triggered reporting of measurements,
the event triggered reporting is triggered based on evaluation of the criterion relating to an event,
the event is related to a measurement reference cell of the plurality of cells,
the one or more of the reporting configurations each include an event identity for selecting the criterion relating to the event; and
the radio resource control circuitry is configured to and/or programmed to:
determine (i) the first cell as a measurement reference cell among the plurality of the cells based on a first measurement object linked to a first reporting configuration corresponding to a first event and (ii) the second cell as a measurement reference cell among the plurality of the cells based on a second measurement object linked to a second reporting configuration corresponding to a second event, and
perform a measurement of the first cell and a measurement of the second cell,
wherein (i) a measurement result of the first cell is used as a measurement result (Ms) of a serving cell in the first event and (ii) a measurement result of the second cell is used as a measurement result (Ms) of a serving cell in the second event.
